IMPROVED CNDENSER FOR STILLS.

To all whom it may concrn:

Be it known that I, H. C. SHERMAN, of the city of Buffalo, county ofErie, and State of New York, have invented certain new and usefulImprovements in Oondensers for Dis tilleries; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings and the letters of referencemarkedthereon, in which- Figure I is a vertical section of my improvedcondenser as placed in the tank, and Fig. II is atop plan of same. w

The nature of my invention relates to the arrangement of a number ofzigzag condensing-pipes side by side in sections and parallel to eachother, each section opening from a transverse supply-pipe at the top andinto a transverse discharge-pipe at the bottom, so that the alcoholicvapors which enter the supply-pipe from the `still Will be divided,equal portions passing through each section of the zigzagcondensing-pipe, making the condensation much quicker and more perfect;second, in connecting the zigzag condensingpipes to the supply-pipe atthe top and to the discharge-pipe at the bottom by means of flanges, sothat either section may be removed for repairing without materiallyinterfering with the operation of the condenser; third, in thearrangenent of a perforated cold-water feed-pipe beneath thecondensing-pipes in such a manner that a jet of cold water will bethrown directly against each section, thus increasing the rapidity andcompleteness of the condensation of the alcoholic Vapors.

Letters of like name and kind refer to like parts in each of thefigures.

A represents the cold-water tank, in which my improved condenser isplaced.

B C D, &(3., represent zigzag condensingpipes arranged in sections, andstanding vertically in the water-tank and arranged parallel to eachother. Each section is separate and distinct from the other. Thesezigzag pipes, as constructed and arranged in sections, gradually lessenin diameter from top to bottom to correspond with the decreasing bulk ofthe liquor as it is condensed.

E represents the transverse supply pipe, placed at the top of the tankinto which the alcoholic Vapors from the still are first received beforepassing into the condensing- Spccifieation forning part of LettersPatent No. 3 1,(i4, dated March 11, 1862.

pipes. It is considerably larger in diameter than the condensing-pipes,the upper ends of which open into it at equal distances apart.

F represents the transverse discharge-pipe, located at the bottom of thetank directly under the supply-pipe E. The lower ends of the condensing-pipes open into this pipe, which is of smaller diameter than thesupply-pipe, corresponding to the lessenin g diameter of thecondensing-pipes.

g represents joints formed in the upper and lower bends of thecondensing-pipes near the supply and discharge pipes, having short partsb c' d', Sto., connected to the supply-pipe and similar parts, I c' d8:0., connected to the discharge-pipe. A flange is formed upon the endof each of these short pipes, and asimilar flange upon the ends of eachof the condensing-pipes, by which they are connected together by meansof bolts. Similar joints may also be formed at the center bend of eachof the condensing -pipes, if desired. Should either of the sectionsbecome leaky or out of repair, this Construction allows of its removalto be repaired, and by-placing a blind flange over the openings of theshort pipes made by its removal the operation of the other sections willnot be interfered with H represents the cold-water feed-pipe, passingtransversely across the bottom of the tank beneath the condensing-pipes,and having a number of holes or perforations therein ,which throw jetsof cold water directly upon the cendensing-pipes, thus using thecondensing power of the cold water to much better advantage than were itthrown in in one large stream.

r represents the waste-water pipe, which earries off the heated water tothe boiler, and prevents the tank from overflowing.

The advantages which this condenser has over the ordinary worm condenserare as followsz First, it is much cheaper of con.- struction; second,with the same amount of material, a much larger condensing-surface isobtained, and it is more evenly distributed through the tank, so that itcondenses more rapidly and perfectly; third, the'tank may be madesmaller, and the quantity of water used will be much less; fourth, incase of leakage in any one of the condensing-pipes, it may be removed,as before described, without inter ferng with the operation of theothers.

What I claim as my inventon, and desir to secure by Letters Patent, is il. Making the condenser of zigzag condensing-pipes arranged side by sidein sections,

and parallel to each other, (or nearly so,) each I section opening inand connected to a trans- Verse supply-ppe {at the top and a transversedischarge-pipe at the bottom, for the purposes and substantially asdescribed.

2. The combination of the sections B C D with the transverse dischargeand supply pipes E and F, each transverse pipo having short pipes b a',and d', 850., and b c (1 &c., to adnit of an easy connection anddsconnection of the sections thereto, for the purposes and substantiallyas set forth. i

3. The combnation and arrangenent of the perfomted cold-water feed-pi peH with a condenser constructed in sections, substantially as set foi'th.
